An effective model for quark masses and mixings

By analogy with an effective model of charged-lepton mass matrix that, with the inputs of m(e)(exp) and m(mu)(exp), predicts (in a perturbative zero o rder) m(tau) = 1776.80 MeV close to m(tau)(exp) = 1777.03 (+0.30)(-0.26) Me V, we construct such a model for quark mass matrices reproducing consistent ly the bulk of experimental information on quark masses and mixings. In par ticular, the model predicts \V-ub\ = 0.00313, gamma = - arg V-ub = 63.8 deg rees and \V-td\ = 0.00785, beta = - arg V-td = 20.7 degrees (i.e., sin 2 be ta = 0.661 to be compared with the BaBar value sin 2 beta (exp) = 0. 59 +/- 0. 14), if the figures \V-us(exp)\ = 0. 2196, \V-cb(exp)\ = 0. 0402 and m( s)(exp) = 123 MeV, m(c)(exp) = 1.25 GeV, m(b)(exp) = 4.2 GeV are used as in puts. Also the rest of CKM matrix elements is predicted consistently by the experimental data. Here, quark masses and CKM matrix elements (ten indepen dent quantities) are parametrised by eight independent model constants, wha t gives two independent predictions, e.g. for \V-ub\ and beta. The consider ed model deals with the fundament al-fermion Dirac mass matrices, so that t he neutrino Majorana mass matrix is outside the scheme. Some foundations of the model are collected in Appendix.
